AUTOMATIC DUMPING APPARATUS.

I SPECIFICATION forming part of Letters Patent No. 508,158, dated November '7, 1893;

Application filed October 27, 1892. Serial No. 450,119. (No model.)

To all whom it may concern.-

Be it known that I, JOHN R. WILSON, a citizen of the United States, residing at Pittsbnrg, in the county of Allegheny and State of Pennsylvania,have invented a new and useful Automatic Dumping Apparatus, of which the following is a specification.

This invention relates to dumping apparatus; and it has for its object to provide an improvement in car-dumping apparatus for use at coal and ore mines, in which efticient means are provided for rapidly dumping the vention is better understood, the same con-. sists 1n the novel construction, combination and arrangement of parts hereinafter more fully described, illustrated and claimed.

In the accompanying drawings:Figure 1 is a side elevation partly-in section of a'dumping apparatus constructed in accordance with this invention, illustrating the dumping track section in its tilted position. Fig. 2 is a top plan view of the apparatus illustrating the apparatus in its normal position about to receive a loadedcar. Fig. 3 is a verticaltransverse sectional view on the line m-x of Fig. 2. Fig. 4 is a detail in perspective of the brake mechanism. Fig. 5 isa detail sectional View illustrating the arrangement and support of the stop horns. Fig. 6 is a top plan View of a modification of the apparatus. Fig. 7 is a detail sectional view on the line 'y-y of Fig. 6. Fig. 8 is a detail sectional view on the line .22 of Fig. 2.

Referring to the accompanying drawings A represents a trestle supported frame of the ordinary type used in dumping apparatus for coal and ore cars, and upon the same is secured the main stationary track rails B, upon which the mine cars after being raised from the mine are designed to travel to the'dumping apparatus herein described, arranged in the line of the main track, and from which the empty cars, after being automatically dumped thereby, are returned in the usual manner to be refilled, over the rails C, of the inclined portion of the main track.

The loaded cars from the main track, pass over the rails D, to the tilting or rocker track section D. The tilting track section D comprises the opposite parallel tilting rails d, which, when in their normal horizontal position, form a continuation of the main stationary rails B, and are connected in their spaced position by means of the intermediate bridles cl, as fully illustrated. To the under side of each of the opposite rails d, of the tilting track section is seen red a rocker shoe E, securely bolted or riveted to the flange and bottom of the rail, and provided with a series of notches a, The opposite rocker shoes E, of the tilting rails, are adapted to rock over the opposite stationary rocker castings F. The rocker castings F, are constructed segmental in shape, and are provided upon their upper faces with the teeth or cogs f, and are adapted to register with the notches in the rocker shoes, so as to provide a secure rocking pivot for the tilting tracks, so that the same does not abruptly tilt as the loaded car overbal- 8o ances the same, but in order to provide an even un precipitous tilt. Said opposite rocker castings F, are located at the end of the frame timbers supporting the main track rails, at the point where the loaded cars are to be dumped, and the rocker connection with the tilting track section is arranged at such a point, so that when the stop devices check the loaded car, the weight of the latter is sufficient to tilt the track section and relieve 9c the car entirely or partially of its contents.

Forming continuations of the inclined and tilting track sections are the drop track rails G. The drop track rails G are halved at their dropping ends onto the dropping ends 5 of the rails d, and are securely connected Y thereto by the transverse pivot rod g, connecting the meeting ends of the track sections to form a pivotal or hinged joint, which breaks downward as the loaded car tilts the tilting track section. The transverse pivot rod g, accommodates the .spacing sleeve 9,

intermediate of the joined rail ends, and

holds the same in direct alignment with each other. The drop track rails G, are provided near their other ends in the web thereof, with longitudinally disposed slotsg working over the stationary transverse supportingrod'H. The supporting rod H, projects beyond the opposite rails G, and has its ends mounted in the boxes h, secured upon one of the frame timbers adjacent to the ends of the inclined rails G, and said rod also accommodates the spacing sleeves h, which provide means for holding the drop track rails in their spaced positions, so that when the track sections are in their normal aligning positions, the rails of the several track sections will form continuations of the same track. When the tilting track section is tilted, and the wagon orcar dumping, the drop rails G, hold the tiltingsection steady,'and when the latter resnntesitshorizonta-l position, said drop rails take theempty'car and lead the same directly onto the inclined track section to carry the'car backto its refilling point.

Fixedly secured to thebottom of the rail d, ashort distance beyond the rocker stipportarethe parallel channel irons or grooved guide bars I. The said parallel guides I, have their grooves facing each other, and extend transversely under the tilting'track section'and project a'sliort distance beyond the op'po'site sides'thereof, in order to accommodate the'sliding blocks J. Thesliding'bloeks J ,"slide between and registehWith'the guides J, which carryn pon their'extreme upper-"ends i the off=standing curved stop and releasing'i home 3'. The o'ppositestop and releasing? horns j, are'adaptedto normally lie directly over'th'e tread or ball of the rails of the track,; so thatthe forward wheels ofthe cartake into thehorns, so'as to hold the car onto'the tilting: track section, until the same has'been' relieved E ofits contents,after which,means'arepro'vided fors'pread-ing the hornsor throwing'the'same outwardly and away'frornthe'rails, so as to releasethe car and allow the same to pass lieyond'the horns, while the n'extlo'aded car is approaching the same.

Depending from the bridle d, and other points ofattachmentare the bearing arms I whichaccommodate the longitudinally disposed-rock shaft L, which is adapted to'be rockedor operated by the loading car'as will be presently described. Fixedlysecn'red to one end ofthe rock shaft L, at a point directly under andbetween the 'guid'esLis the 'oscillatingcross-lever Z, tothe opposite ends of which are pivotally 'securedthe opposite, 'or upper-"and lower spreading rods or arms 'M. lhespreading rods or arms M, are pivotally'connected attheir outer ends as at m, tothe'innerends ofthe slidinghorn blocks,. J sdthatas the shaft L, is rocked in'onedirection, by the loaded car, the cross-lever Z, throws the rods, M, in opposite directions,

I, and are each providedo'utside ofthe oppositefrailsdfivith the'upwardly extendi'ngartns and therefore 'spreadsthe opposite horns, to release the empty car from the tilting track section as herein described, and after the empty car has passed from the tilting sec tion, the rock shaft, L, is rocked or turned back in the opposite direction by means of the retractile spring N, connected at its ends to one of the rails d, and to the arm n, projecting from the rock shaft L, and thus provid ing means for automatically returning the sliding horns to their normal position above the rails to catch and hold the nextloaded car.

One of the rails d, has the ball or tread thereof cut away for a portion of its length at one end as at O, in order to accommodate the tread lever 0, which is designed to register with said cut away portion and form the tread or ball of the rail at this point when lowered or pressed down by the wheels of the loaded'car or wagon. The tread levero, is provided at one end with the pivotlugs 0', which embrace the web of the rail and are pivoted or fnlcrumed thereto on the pin 0 'as'clearly illustrated in the drawings. The treadlever o, asnoted, corresponds inshape to the'tread or'ball of the rail, and thesanie is further provided at itsswinging end with the U shaped yoke 0 fixedly secured to the underside thereof and adapted to embrace the web of the rail. Pivotally securedatits 'upperend to one ofthe jaws of'said yoke is "the operating bar P, provided near its lower endwith aslotor opening 19, which receives "the outerend oftherock arm'p', fixedly secured'at'its otherinnerend-to t'hero'ckshaftL, and providingnieafns forpositively rocking'the shaft L,in one dire'ctionya's thetread"leveris pressed down bythe'lOadedc-ar. Fixedly se- "cured to the other'opp'osite jaw of the'yoke 0 idtheop'posite guideba'r'or'arm picorrespond- *ing to the bar P, and together with'thesanie, *forming a yoke guide andbrace for the tread lever 0, to hold the "same to its up and down movement as'is e'leai'ly illustrated in Fig. 8 of 'the drawings. Now it"will beapparent, that, after a loaded'car'has'been'relievedof itscontents and the tiltinganddrOpWrack sections have resumed their normal h'o'rizontahposi- *tions, theadvancing loaded car willp'ress the 'lever 0, into alignment'with the railand there- 'byspread'theh'orns awayfroin "the =rails,so thattheloaded car willbnmp the einpty ca'rolf of the dump, and after the rear w'heelsofsaid 'loaded'carpass-thetread 1ever,the retractile spring N, immediately withdraws the" horns totheir normal position in time tostop" and 'hold the loaded car; sdtIiattheOperatiOn can be repeated automatically, as will berea'dily "apparent.

Depending from the'end"bridlesa*tone end of the tiltingtracl; section are the lugsQ,"between which is pivotedoneendofthe link q, to the other'end' of which is" pivoted one end of the brake bar q',wh'ich by the mechanism to be deseribed'isadapted to regulate'theabruptn'ess orsuddennessof the 'tilt, and also 'toease the jar of the tilting track section returning to its normal position.;-'Phe otherlower end of the brake bar g, is fixedly bolted as at (1 to the movable friction disk or wheel R. The friction diskor wheel R, is loosely mounted to turn on the stationary stub shaft or axle r, secured transversely of thetrack frame and having its inner. end connected to the stationary brake disk r which latter is securedly bolted to an intermediate frame timber A. The stationary brake disk 1- is provided upon its upperedge with the pivot lugs r between which is pivoted the inner end of the .brake'weight lever S. :Theweight lever S, carries upon its outer free, end the weight 8, and is provided at an intermediate point with a bifurcated arm .9, which is adapted to embrace the shaft or axle r, and under the pressure due to the Weight, bear against one end of the spring '1, mounted upon the axle r, and the other end of which bears againsttheturning disk or wheel R, and holds the same in contact with the stationary disk or wheel, so as to cause sufficient friction, to

secure the proper braking of the tilting track section. Various sizes .of weights 5, may be used as found necessary. 1

The weight may be lifted or eased from the brakedisks by any suitable means, as illustrated, in which I have shown a bell crank lever U, pivoted to a suitable point of attachment andhaving one arrnthereof bearing un-' der the lever S, while the other arm thereof is connected by the link at, withan operating Which Will-be readily under-' handle lever it, stood.

. In order to prevent the coal or ore from dropping between the rails of the'tilting track section as described, I slightly modify and add tothe construction just described,- as illustrated in Fig. 6 of the drawings.

of the rails 61, as illustrated, in order to accommodate the transverse dead or chute plate V. TheplateV, extends transversely under and incloses the entire space between the extended portions of; the, rails d, and extending beyond the outer sides of theirails is provided with-the upturned side flanges W, which project above the plane of the rails and form an inclosed chute, which throws the contents of the car at an angle from the tiltingtrack section, while at the same time the side flanges W, serve in the capacity of side; guards for the car. Bracing strips X, extend trans- .versely under and across the chute plate,and

In this modification-I dispense with the drop track rails G, and in lieu thereof extend the ends described automatic dump, will be readily apparent to those skilled in the art. Itwill be observed that in Fig. 1, I have shown in dotted lines the position of the chute endof thetilting rails when the drop trackrails are dispensed with as shown in the modifications in Figs. 6 and '7.

Changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of the inveution. I
